COMPRESSION MEANS FOR. FOUNTAIN-PENS.

Specification of Letters Patent.

Patented Dec. 24, 1912.

Application filed November 3, 1911. Serial No. 658,374.

To all whom it ma concern:

Be it known t at I, EDWIN B. SMITH, a citizen of the United States, residing at Paris, in the county of Lamar and State of Texas, have invented a new and useful Compression Means for Fountain-Pens, of which the followin is a specificatlon.

It is the object 0 this invention to provide a fountain pen having novel means for compressing the reservoir of the pen.

Specifically, the invention aims to prov1de a compression member for a pen, which com pression member, in addition to its ObVlOllS function, will serve, as well, as a means for maintaining in the barrel of the pen, the head wherewith the compressible reservolr and ink-applying elements are connected.

A further ob ect of the invention is to provide a fountain pen with separate elements, each of which may be operated mdependently, to compress the reservoir, one, of said elements constituting a means for mani ulating the other.

ith the foregoing and other objects in view which will appear as the description proceeds, the inventlon resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departin from the spirit of the invention.

In t e accompanying drawings,-Figure 1 shows the invention in longitudlnal section, parts remaining in elevation; Fig. 2 is a transverse section upon the line 22 of Fig. 1; Fig. 3 is a transverse section upon the line 33 of Fig. 1; and Fig. 4 is a plan of the barrel and certain of .its accessory parts, portions being sectioned;

In carrying out the invention there is proopen at both ends, and ordinarily of cylindrical contour. Adjacent its forward end, the barrel is provided with a longitudinally extended slot 2, of considerable length. In one end edge of the barrel 1 there is a notch 3. Adjacent the other end of this barrel 1, but located entirely within the contour of the barrel, is a slot 4, which is somewhat shorter than the slot 2.

her, longitudinally of the barrel 1.

Located within the barrel 1, slightly in advance of the slot 4, is a shoulder 5, against which bears one end of a helical compression spring 6, the outer end of which bears against a tubular cap 7, adapted to slide in one end of the barrel 1. A screw 8 is in serted into the side wall of the cap 7, the screw 8 being adapted to move in the slot 4, the screw 8 serving to prevent the cap 7 from being thrust entirely out of the barrel 1, by the action of the spring 6. The cap 7 is e uipped in its interior with a transverse, inclined wall 9, located at an angle to the axis of the barrel 1.

Into the other end of the barrel 1 is inserted a head 10, provided at its inner end with a bulb 11, adapted to receive and to retain the open end of a compressible reservoir 12, located within the barrel 1 and extended into close relation with respect to the inclined wall 9 which is carried by the cap 7. The outer, exposed end of the head 10 is flattened, as shown at 14, and the blades 15 of the pen, constituting the ink-applying elements, are applied to opposite faces of this fiat portion 14 of the head. The blades are connected by a pivot element 16 with the portion 14 of the head, the blades being united, as usual, by the adjusting screw 17.

A feed tube 18 enters the head 10, the tube 18 carrying a cleaner 19. The tube 18 communicates, through the bore 20 of the head 10, with the interior of the compressible reservoir 12. The construction is such that the blades 15 may be swung to one side, upon their pivotal mounting 16, so that the tube 18 may be inserted readily into a source of ink-supply. Inserted radially into the head 10 is a pin 21, the pin 21 being adapted to enter the notch 3 in the end of the barrel, to prevent the head from rotating in the barrel. In one side of the head 10 there is a longitudinally extended groove 22.

The invention further includes a compression member, denoted generally by the numeral 23. This compression member 23 includes a shank 24, adapted to enter the slot 2, and provided with a shoulder 25 which may engage one end wall of the slot 2, to limit the movement of the compression mem- The of the compression member 23 is spaced apart from the barrel 1 and is angularly disposed with respect thereto, as indicated at 28, the construction being such that the finger of the operator may be placed uponv the part 28, to effect a movement of the compression member 23,"and consequently to effect a compression of the reservoir 12. Secured to the forward end of the portion 28 of the compression member is a rearwardly extended, wedge-shaped tongue 29. This tongue 29 is adapted to engage'in the groove 22 of the head 10,'the wedge-shaped tongue 29 constituting a means for holding the head 10 engaged,with the barrel 1. The compression member 23, broadly considered, comprises angularly disposed parts 26 anti 29, one of which parts is adapted to bear upon the compressible reservoir 12, the other of which parts constitutes a means for holding the head 10 in the barrel 1. e

The practical operation of the device is as follows: The finger of the operator may be placed upon the portion 28 of the compression member 23, the compression member being operated in this manner, so that its portion 26 will bear upon the reservoir 12, for the purpose of expellingthe ink, and for the purpose of expelling the air from the empty reservoir, so that the ink may be sucked thereinto, it being understood that the reservoir 12 is not only compressible, but resilient, as well. The reservoir 12 may be manipulated, also, by thrusting the cap 7 inwardly, so that the inclined wall 9 of the cap 7 bears against the closed end of the reservoir 12. Moreover, when the cap 7 is thrust inwardly, the inclined wall 9 of the cap will engage with the beveled end 27 of the portion 26 of the compression member 23, thrusting the portion 26 of the compression member against the reservoir 12. "It has been found in practice that the reservoir 12 cannot be emptied completely by the operation of the member 23, for the reason that the portion 26 of the member 23 will not flatten the reservoir 12 adjacent its closed end. This closed end may be flattened through the operation of the cap 7, but if the cap 7 is operated alone, the forward portion of the reservoir 12 will remain uncompressed. In the present construction, when the cap 7 is thrust inwardly, the compression member 23 will be moved into engagement with the reservoir 12. Thus, the reservoir 12 will be flattened out,v throughout practically its entire length, by the member 23, and, at the same time, the reservoir will be subjected to endwise compression, due to the engagement between the wall 9of the cap 7, and the end of the reservoir 12.
